Problem: Neither on-screen menu nor other
external programmes appear on the
TV screen. TV only shows those
stations which are received via its
own aerial.
Cause 1: Video lead not connected properly.
Remedy: Push in all connectors firmly.
Cause 2: The TV set does not switch
automatically to the AV input.
Remedy: Set the TV set to 'AV operation' mode.
Problem: Picture unstable.
Cause: Synchronisation signal absent.
Remedy: Push connector in firmly, or set
television to 'AV operation' mode.
Problem: Monochrome picture only.
Cause: Incompatible picture norms set on the
TV, the decoder and the source device.
Remedy: Set TV, decoder and source device to
the same picture norm.
Note: If problems persist, set the decoder to
the 'RGB / Video' norm; select the
picture norm 'Video', occasionally also
termed 'FBAS' or 'Composite', on the
TV set and the source device.
Problem: Nothing on the decoder screen.
Cause: The screen is switched off.
Remedy: Switch the screen on again in the
'
Configuration Menu'.
Problem: When playing an NTSC-DVD the on-
screen menu is distorted.
Cause: The TV set does not feature automatic
format detection for NTSC, and has
been set manually to NTSC. The
SR 1535 R’s
on-screen menus are only
generated in PAL format, so this
operation is not possible.
Remedy: Use a TV set with automatic PAL /
NTSC format switching, or use the
surround receiver’s integral screen.
Problem: Picture correct, but no sound audible
through the decoder.
Cause 1: No sound connection between source
device and decoder.
Remedy: Complete the sound connection
(analogue or digital depending on
mode);
see section entitled
' Installation, wiring and using the
system for the first time'.
Cause 2: No sound input, or the wrong sound
input, has been assigned to the picture
input in the 'Source Setup'.
Remedy: Check the sound input to which the
source device is connected. Call up the
'
Source Setup' and carry out the
correct assignment.
Cause 3: The loudspeaker is switched off.
Remedy1: Switch on the loudspeaker using the

  button.
Remedy2: Check that the decoder has not
switched itself off due to overheating or
a short-circuit in the loudspeaker
connection.
Problem: When you switch television
programmes, you hear unwanted
noise.
Cause: The television set is not capable of
muting (silencing) the SCART audio
outputs.
Remedy: Connect the audio output (Cinch
sockets) on the TV set to the pre-
amplifier’s TV audio input. In the AUDIO
column of the 'Inputs Menu' you must
now select TV instead of TASI !
Note: This variant on standard wiring is
possible with all source devices for
which a corresponding pre-amplifier
input is available.
Problem: Decoder switches off after a certain
period of operation.
Cause: Unit is overheating.
Remedy: Make sure that the cooling airflow is
adequate; reduce volume if necessary.
